Suspended Matter

Types Of Water Pollution

Some pollutants do not dissolve in water as their molecules are too big to mix between the water molecules. This material is called particulate matter and can often be a cause of water pollution.


  • The suspended particles eventually settle and cause a thick silt at the bottom. This is harmful to marine life that lives on the floor of rivers or lakes.
  • Biodegradable substances are often suspended in water and can cause problems by increasing the amount of anaerobic microorganisms present.
  • Toxic chemicals suspended in water can be harmful to the development and survival of aquatic life.
